Cardiorespiratory endurance is defined as:

Cardiorespiratory endurance specifically refers to the ability of the cardiovascular and respiratory systems to supply oxygen to muscles during sustained physical activity. This definition aligns closely with the first choice, which emphasizes the capacity to engage in large-muscle activities for extended periods of time.

When a person has good cardiorespiratory endurance, they can maintain physical activity for longer durations without excessive fatigue. This endurance is typically developed through aerobic exercises such as running, cycling, or swimming, which utilize large muscle groups continuously, thereby enhancing the efficiency of the heart, lungs, and blood vessels.

In contrast, the other options describe different concepts related to fitness. The ability to recover quickly from exercise speaks to aspects of overall fitness but does not directly define cardiorespiratory endurance. The maximum weight one can lift relates to muscular strength, which is entirely different from endurance. The strength of the heart muscle pertains to the muscular capabilities of the heart itself, rather than its efficiency in delivering oxygen during aerobic activity. Thus, the first choice accurately encapsulates the definition of cardiorespiratory endurance.
